Abstract: The disclosure relates to obstacle array devices (also known as bump array devices) for separating populations of particles by size. Improvements over previous obstacle array devices are realized by causing the fluid velocity profile across gaps between obstacles to be asymmetrical with respect to the plane that bisects the gap and is parallel to the direction of bulk fluid flow. Such asymmetry can be achieved by selecting the shape(s) of the obstacles bounding the gap such that the portions of the obstacles upstream from, downstream from or bridging the narrowest portion of the gap are asymmetrical with respect to that plane. Improvements are also realized by using obstacles that have sharp edges bounding the gaps. Other improvements are realized by selecting obstacle shapes such that the critical particle dimensions defined by the gaps in two different fluid flow directions differ.

Abstract: Membrane elements that use multiple membrane leaves may have a limited total active membrane area due to an increased diameter at the ends of the element. Membrane leaves may comprise a permeate carrier positioned between one or more membrane sheets. Adhesive may be used to seal one or more edges of the membrane leaf. The membrane sheets, permeate carrier and the adhesive contribute to the thickness of the edges of the membrane leaf and the diameter at the ends of the element. A reduced thickness of the edges of the permeate carrier may reduce the diameter at the ends of an element. Another permeate carrier sheet may also be used that is distanced from at least one edge of the membrane sheet so the permeate carrier sheet does not contribute towards the increased diameter at the ends of the element.

Abstract: The various embodiments herein provide a method for evaluating a performance of lime softening clarifiers. The method is based on electrical conductivity (EC) measurement of the treated water samples after addition of carbon dioxide. If EC of the treated water after carbon dioxide gas addition is lower than EC of the treated water, this shows an abnormal function of softening process and the lime dosage must be decreased. If EC of the treated water after carbon dioxide gas addition is higher than EC of the treated water, then the lime dosage is not enough and lime dosage must be increased. If EC of the treated water after carbon dioxide gas addition is roughly equal to EC of the said treated water, then the lime dosage is optimum and clarifier works in optimum condition.
